Quantitative complementarity between local and nonlocal character of quantum states in a three-qubit system
Xinhua Peng, Jingfu Zhang, Jiangfeng Du +1
Local or nonlocal character of quantum states can be quantified and is subject to various bounds that can be formulated as complementarity relations. Here, we investigate the local…
Complete Adiabatic Quantum Search in Unsorted Databases
Nanyang Xu, Xinhua Peng, Mingjun Shi +1
We propose a new adiabatic algorithm for the unsorted database search problem. This algorithm saves two thirds of qubits than Grover's algorithm in realizations. Meanwhile, we anal…
A Non-Oracle Quantum Search Algorithm and Its Experimental Implementation
Nanyang Xu, Jin Zhu, Xinhua Peng +2
Grover's algorithm has achieved great success. But quantum search algorithms still are not complete algorithms because of Grover's Oracle. We concerned on this problem and present…
Quantum simulation of a system with competing two- and three-body interactions
Xinhua Peng, Jingfu Zhang, Jiangfeng Du +1
Quantum phase transitions occur at zero temperature, when the ground state of a Hamiltonian undergoes a qualitative change as a function of a control parameter. We consider a parti…
A Quantum Adiabatic Algorithm for Factorization and Its Experimental Implementation
Xinhua Peng, Zeyang Liao, Nanyang Xu +4
We propose an adiabatic quantum algorithm capable of factorizing numbers, using fewer qubits than Shor's algorithm. We implement the algorithm in an NMR quantum information process…
Experimental demonstration of deterministic one-way quantum computing on a NMR quantum computer
Chenyong Ju, Jing Zhu, Xinhua Peng +3
One-way quantum computing is an important and novel approach to quantum computation. By exploiting the existing particle-particle interactions, we report the first experimental rea…
Measuring complete quantum states with a single observable
Xinhua Peng, Jiangfeng Du, Dieter Suter
Experimental determination of an unknown quantum state usually requires several incompatible measurements. However, it is also possible to determine the full quantum state from a s…
